Application led 'February 21, 1917. Serial No. 149,981.

To all whom t may concern:

Be it known that I, HARRY S. a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, :have invented certain new and useful Improvements in Agricultural Implements, of which the following is a 4specification, reference being had therein to the accompanying drawing.

This invention relates to agricultural implements and has reference more particularly to seed planters of the single-row lister type comprising a frame sustained at the frontby ground wheels and at the rear by covering or press wheels and giving support to a furrow opener in the form of a f double mold board plow, charging mechanism, the machine operating lto make a furrow in which the seed is deposited, and acting to throwv up` the soil at leither side of'the furrowl so as to form alternate ridges and trenches. Owing to the fact that in these machines the double mold board plow presents aneXtended surface to the ground in making the` necessary furrow and in throwing up the dirt, considerable difficulty is encountered in raising the plow by hand., One feature of my invention aims to overcome this difficulty, andy one part of the invention consists in mechanism of improved form and construction for raising the plow by power derived from the motion of the machine through the field, the said power being taken preferably from one of lthe ground wheels.

' A vsecond 'feature of the invention consists in improved means for sustaining the furrow opener support or plow beam so that it may be raised and lowered, and adjusted to 40 maintain its proper position when raised and lowered,-and to vary the angle of the plow point tothe ground according to' the nature of the soil, whether hard or soft.

The invention 'consists also of various other improved features of construction designed to simplify the construction and opleration of the machine as a whole and to DroKiNsoN,

render its action reliable and effective, which improvements will be fully set forth in the specification to follow andthe novel parts of which will be delined in the appended In the accompanying drawings:

F ig. 15 is a fragmentary perspective View showing how the arched axle isI mounted at oneside in its bearing in the machine frame to permit ofthe relative adjustment of the frame to cause the press wheels to follow the furrow accurately.

Referring to the drawings:

The frame of the machine in the present instance consists of two horizontal fore and aft extending parallel frame bars 1 and 2 which converge at their rear ends and are connected together by a casting or block 3 provided with a vertical bearing 4 for the purpose presently to be described. The frame bars at their forward ends give support to a horizontaltransverse` draft bar 5 to which is connected a draft tonguez The forwardend of the frame is sustained at one side by a ground wheel 7 and at the other side by a ground wheel 8', which wheels are mounted to rotate on the horizontal axle arms 9 of an arched axle 10, the central l arched portion/of which, comprising-the arch arms 10a and l()b and connecting wrist 'pori tion 10C, is situated between the frame bars l and 2, while the horizontal axle arms are mounted loosely in bearings 11 and 12 supy ported in brackets or hangers l2a and 12b depending from the two forward ends.

The rearend of the frame is a press wheel structure wheels 14 mounted on zontal axle 15 on the lower end of a vertical stem 16, the upper end pf which is mounted loosely in the bearing 4 before alluded to, so that the press wheels may swivel about the vertical axis of the` stem. Beneath the bearing 4 the stem has fixed to'Y it a collar 4L containing a notch 4b in its periphery,

frame 'bars near their supported by comprising two press vwhich notch, is adapted to, receive a horizontally endwise movable locking latch 4c mounted in guides 011 the'under side of the block 3, the said latch being acted on by a spring 4d which tends to thrust it rearwardly against the periphery of the collar and seat the latch in the notch. The latch and notch are so arranged with relation to the machine frame and axle l5 that when the latch is engaged in the notch, the press wheels will be held from swiveling so that they will travel in line with the path 'of advance of the machine. The sides of the latch are beveled and the walls of the notch are like wise beveled so that if the wheel encounters undue resistance or pressure, tending to turn the same and swivel the stem, the latch will be automatically'pushed forwardly and disengaged from the'notchso as to release Ithe stem and prevent injury to the parts. -Provision is made for retracting the latch to release the stem so that the wheels may casterv this position by the latch the ends of a hol-i-.

capable of a limited endwise movement thereon. At its forward end the lever has connected with it a link`,4h which extends rearwardlyand has its rear end jointed to the rear end of the latch.` Near its rear end the lever has pivoted to it a second link 4i which extends rearwardly and is'pivoted as at 4j to the block 3. Normally, vwith the latch seated in the notch in the collar, and held therein yieldingly by the spring, the footlever will extend at an upward inclination and` will be maintained yieldingly in spring. When now it isdesired to release the stem to permit the press Wheels to caster freely, ator presses down on a lateral foot pad 4k on the rear extremity of the lever, which action-will swing the lever and link 4h downwardly and at the same time will shift the'/ lifts the foot pad upwardly with his toe,v

thereby breaking the locked condition of the parts and permitting the latch spring to again project the latch rearwardly into active position. i

17 designates 'a fore and aft extending plow beam or furrow opener support having applied to its opposite sides depending brackets lconstituting in effect abracket arm in which the central wrist portion ofthe arched axle l0 Iis loosely mounted, so that when the said arched portion is swung up Aand down in its bearings, the said 'beam will 4be moved up and down relatively to the machine frame as is usual in machines of this type. The plow beam has connected with its rear end a furrow yopener in the form of a double mold .board plow 19 and it carries also a. sub-soiler 2O for formin the trench in Awhich the seed is depositec, the said seed being stance by disk coverers 21 .traveling in rear vof the subsoiler, and the soil being pressed the opercovered inv the present indown on the seed bythe press wheels 14 be- 12.

fore k'alluded to.

The seed is directed into 'thetrench by a verticalI seed tube 22 sustained at its lower end'by the rear end o`f the `beam and ex? f tended at its upper end between the frame la bars of the machine in position to receive the seed delivered by the seed discharging mechanism inthe bottom of a seedv can or hopper 23. The seed can is supported from the frame bars by a bracket or frame 24 firmly connected with the frame bars by means of the vertical standards 25, and a horizontal seed shaft 26 is mounted in suitable bearings in the frame. 24 and in a standard 24extending upwardly from the frame bar 1. The shaft carries a vertical bevel pinion 27 which meshes with a horizontal bevel pinion 28 operatively connected with and driving the seed discharging mech-v anism. t 'y l The seedshaft receives its motion from the ground .wheel v'7 which has connected 4with it a sprocket wheel 29 which rotates with the ground wheel. A sprocket chain 30 passes around the spocket wheel29 and around a sprocket wheel 31 mounted loosely on the outer end of a horizontalcountershaft 32, extending parallel with and in rear of the seed shaft and mounted in bearings in the standard 24at before alluded to, and

- in an arm 33 extending upwardly from the j tion is adapted to the spring Vl Y will be presently `adapted 4to longitudinally frame barl 1, the said counter-shaft being operate 4the seed discharging mechanism through driving ently to be described. The 31 has xed to its inner side a driving clutch member 31a which is adapted, when the sprocket wheel -isrotated in the-advance of end of the shaft, the tendency of the spring being to maintain the engagement ofthe while permitting the` two clutch members, wheel to be lnovedjagainst the pressure of to disengage the clutch.

means of this 'clutch mechanism, the seed discharging mechanism will not be driven `when the machine is thrown out ofaction at thewill of the driver during the 'advance of the backed; and it may be machine, 'and also automatically when the plow is raised, as

described.

, The counter-shaft 32 has splined to it a spur pinion 34 and of the shaft, which pinion is in constant mesh'with a transmitting spur pinion 35 mounted loosely between parallel arms 36 of a lever 37. The forward ends of the arms of this on the coluntershaft at opposite sides of the spur pinion 34, sosthat by shifting the lever gearing Vpressprocket wheel' 44 of respectively the machine frame in which may be shifted lever are mounted loosely .pressions 46 and horizontally the pinion 34 and transmittin pinion will be correspondingly shifted an the latter pinion brought opposite to any one of three driven pinions 38,39 and 40 lixed on the seed shaft; and byrocking the lever 37 up and down on the axis of the shaft32, the transmitting pinion may be caused to engage respectively with said driven pinions. The pinions 38, 39 and 40 are of diiferent diam eters in order` to impart different speeds of rotation to the seed shaft, according to t which particular one of the pinions is engaged by thev transmitting pinion. Vhen the lever is shifted and set to engage the transmitting pinion with the smaller pinion 38, theI seedshaft will be driven/at a l higher rate of speed, and when engaged with thelargerpinion- 40 the shaft will be driven at a lower rate of speed, and when engaged with the pinion 39 the shaft will be driven at a moderate rate of speed. v The mechanism described constitutes ,a changeable V,speed gearing for varying'the action of the seed discharging mechanism in o-rder that the seed deposited in` the vground may be e spaced at shorter or longer intervals accordj ing to the condition of the soil. The lever 37 is held .in its diiferent positions of adl justment so as to control the engagement of the transmitting pinion with one or the other of the 'pinions on the seed shaft, vby means of a lug or nose 41 projecting up'- wardly therefrom and adapted `to be engaged in any one of three notches 42, 43 and different depths, in the lower edge of a'member -fix'ed relatively to 45 extending over and inclosing the three pinions. The notch 42 ofthe lesserdepth is arranged opposite thelarger pinion 40, and

the form of a casing l Y when the nose of the lever is engaged in this notch and lifted upwardly, with the nose engagingy the upper'wall of the notch, the

transmitting pinion will mesh with the larger pinion 40 and the motion ofthe ground wheel will be transmitted to the seed shaft through the sprocket wheel 31, spur pinion 34, transmitting pinion 35 and larger driven pinion 40 at a reduced speed. In changing to a higher speed the hand lever 37 is depressed .to disengage its nose from the notch 42, which will disengage the transmitting pinion from the pin ion 40, and -thelever is then shifted horizontally and its nose brought opposite say. the notch 44 of the greatest depth, and the lever being raised and the nose being drawn upward in said notch, the transmitting pinionwill :beengaged with thev smaller pinion 38,'and the motion yof the ground wheel will be transmitted to the seed shaft at a greater speed; The lower edge of the`casing between the several notches is formed with de- 47 adaptedto receive the nose on the leverand hold the' transmitting be maintained in iis ` present machine g Y corn, and is of such form and construction pinion disengaged from either of the three pinions onthe seed shaft, this position of the lever being for the purpose of disconnecting the seed ing andpreventing the action of the seed 'discharging mechanism.

The seed discharging'mechanism of the is adapted for planting as is well known in this art, thata given number of kernels is dropped periodically so as to plant the hills at predetermined intervals. By increasing the speed of the mechanism. or decreasing the same, it will o the planting of the seed in hills in this manthe sleeve is oscillated ner, but is applicable as well in connection with seed discharging mechanism where the seed is drilled7 or planted continuously, the variation in the speed causing a greater or less amount of seed, as the case may be, to be deposited in the ground for a given distance of advance of the machine. i

I propose to utilize the capability of the sprocket wheel 3l to shift on its shaft, to throw the seedV discharging mechanism `out of action automatically when'the'plow bea-m is lifted to raise the plow out of the ground. This is effected by means of a clutch operat; ing member in the form of a vsleeve 49 which loosely surrounds the clutch members 3la and 31b before alluded to, and has its outer end arranged adjacent the inner side of the sprocket wheel 3l. This sleeve is formed at its inner end with sloping teeth 50 which"en gage corresponding teeth'51 projectingoutwardly from the bearing 1n the'standard 24a' in which the counter-shaft is mounted. The sleeve 49 vis both oscillatable and movable endwise on the clutch members, the relation and form of the teeth being such that when rearwardly, it will be forced outwardly, with'the result that ,the

vouter end of the sleeve engaging the sprocket wheel, `will push the same axially and disengage the driving clutch member 3111 thereon from the driven clutch memberlb on the counter-shaft, and the sprocket wheel will then revolve without imparting motion to the counter-shaft, and the operation of the seeding mechanism will be' arrested.

The sleeve 49 has projecting upwardly from it an arm 52, to the upper end of which is jointed the rear end of a link 53 which extends forwardly and is jointed at its forward end to an upright arm 54 of an elbow lever 55,. This elbow lever is pivoted to the frame barl on a horizontal transverseaxis by the shaft from its driving gear` driver, or automatically by the power of the wardly from the frame simple,

pivot bolt 56, and the horizontal arm 57 of the elbow lever projects forwardly and is provided with an inwardly extending finger 58 whichextends above and in the path of the arch arm 10a o'f the arched axle.

As a result of the foregoing construction,

when the arched axle 10 is swung upwardly to'raise the plow beam in the manner to be more fully described hereinafter, the arch arm l0d will engage the finger 58 on the elbow lever and will rock said lever on its axis, which action will'thrust the link 53.

rearwardly and correspondingly swing the arm 52 in a like direction, thereby rotating the sleeve 49 and disengaging the clutch member on the sprocket wheel 3l from the clutch member on the counter-shaft.

In the event of its being desired to disengagey the seed discharging mechanism independently of its automatic disengagement bythe elevation of the beam, .the driver may reach down and swing arm 52 to the rear by hand. The'arm 52 1s acted on by .a spring end to the arm and at its forward end to a gear casing 64 fixed to the machine frame and inclosing the driving sprocketchain and wheels, the tendency of the spring being to hold the sleeve 49 in its forward position with its outer end disengaged from the vsprocket wheel and the latter in driving engagement -with the counter-shaft.

The mechanism described constitutes a durable and effectively operating means for controlling the operation ofthe seed discharging mechanism both automatically by the elevation and manually by the driver, and'by` arranging the operating parts of this mechanism at a point remote from the ground wheel axis, the parts are well removed from the surface of the soil,'thereby avoiding the liability of the yoperative mechanism becoming clogged with dirt and trash.

The Iplow beam and connected parts are adapted to be raised either manually by the machine in its advance through the iield.

`The elevation of the beam manually'is controlled by a hand lever 65 which is pivoted between its ends as at 66 to a toothed segment frame 67 fixed to and extending upbar 2, the said lever being provided below its pivotal axis with a downward extension 68, the' purpose of which will presently appear. Eixed to and extending forwardly from the lever is a bracket arin 69 consisting of an upper'strap 70 connected at its rear end with the lever at a point above the axis 66 as'at 70a, and a lower strap 71 connected at its rear end with the extension 68 of the lever below the axis as `at 71a, the forward ends of said straps being` fastened together by means of a lateral finger 72 on the upper end of a link Leidens 73, which finger extends through holes in the ends of the two straps. The lower end of the link 7 3 is jointed to a plate 74 firmly clipped tothe arch arm .'10b of the arched axle, these parts beam support, constituting in effect a p1votal connection between the lever and beam support. As a result of this construction, when the lever 65 is vpulled rearwardly from its forward position as shown in Fig. 1 to its rear'position as shown in Fig. 2, the link 7 3 will be drawn upwardly and the arched portion of the arched axle will be swung upwardly about the axes of the ground wheels, thereby `elevating the beam Aand raising the plow and connected parts out of action to an elevatedposition as shown in Fig. 2. The segment frame is provided with a series of forward notches 75 and with a single rear notch 76, which notches are adapted to be engaged by the lower end of a locking latch .77 mounted to slide in a lower guiding lug 77' and an upper guiding lug 7 7 b on the hand lever. At its upper end the latch is coupled with a head in the form of an eye 78 on the lower end of-a latch rod 7 8a which rod `extends upwardly and is connected at its upper end with an operating handle 79 mounted on the hand lever. When the latch is engaged with one of the forward notches as shown in Fig. 1, the plow beam and connected parts will be held down with the plow in action, and when engaged with the rear notch 76, the plow beam and connected parts lwill be held in elevated position with the plow out of action as shown in Fig. 2. ln the up and down movements of the beam it is guided and leveled by means of a link 8O jointed at its forward end as at 81 to the rear end of a bracket 82 fixed to the forward end of the machine frame, and jointed at its rear end to a bracket arm 83 extending upwardly from the plow -beam and consisting of two straps 81 and 85 bolted at their lower ends to the plow beam and connected together at their upper ends by means lateral finger 86 on the link 80 extending y through openings in the ends of the straps,

this connection of the link with the straps forming in effect a'pivotal connection between the frame and the plow beam. .The form and relation of these parts is such that when the beam is inxelevated position with the ground wheels and press wheels at the same level as shown in Fig. 2, the bottom of the plow will be in substantial parallelism with the surface of the ground, and when the'beam is lowered the plow will assume a downward inclination at itspoint so as to readily penetrate the soil, and when the furrow has been opened and the press wheels descend to the ioor thereof, the plow as it completes its descent and reaches its working depth, will take the position shown in Fig. 1 with its bottom parallel with the surface joining the lever 65 to the of a' of the lground and bearing latly on the furrow floor. These actions are brought about by the relations which the arch arms 10 bear to the link 80, the latter being, as shown in the several igures of the drawings, less in length than the arch arms. Due to this fact, the plow bottom will assume a horizontal ,level position when lowered into the ground, and this horizontal position will be maintained notwithstanding the increased depth to which it may be set for deeper furrows. n .7. Y The link is provided with a turn buckle 80a by means of whichit may be' lengthened or shortened, the effect of which 80 will be to adjust the plow beam Ion its point of pivotal connection with the arched axle and thereby vary the angle of the plow point'with reference to the surface of the ground. This capability of adjustment l consider of special advantage and importance, .in that' it enables the plow bottom to be set to vproperly take the ground without regard to the wear `on the point oc-A curing in use. Also it enables the angle 0f the plow to be varied according to the coni dition of the soil, a greater tip of the plow point downward being desired when working in hard ground than when working in softer ground.

The elevation of thebeam and connected parts 4by power as before alluded to, is effected by the rotation of the ground wheel 8 yas the machine is drawn through the field. For 'this purpose a friction clutch member 87 shown more particularly in Figs. 4, 6 and 7 is fixed to the inner side of the hub of the ground wheel so as to -rotate therewith loosely about the horizontalaxle arm 9. Cooperating with the clutch member 87 is a clutch drum 88 consisting of a hub portion 88a constituting a winding drum, and a friction rim 88h adapted when the drum is moved toward the clutch member, to frictionally engage therewith and be 110 driven thereby, and when moved away from the clutch member tol disengage therefrom and come to rest. A spiral spring 89 encirclesthe axle arm -between the clutchv member and the clutch drum and tends to urge 1'15 the clutch drum away from the clutch member out of engagement therewith. The clutch drum/rotates loosely on a cam sleeve 90 and against a peripheral shoulder 91 on l the sleeve, which sleeve is mounted 120 loosely on the horizontal axle arm and is provided on its inner edge with sloping cam surfaces 92 engaging corresponding sloping cam surfaces 92a projecting rom the outerI side of the bearing 12 in which '125 the arched axleis supported at one side by the machine frame. The form and relation of the cam surfaces -on the sleeve and the bearing are such that when the sleeve is turned rearwardly it will be thrustf outf 130 f wardly and 'acting on the clutch drun the latter will be forced outwardly towar the clutch member and intol dr1v1ng engagement therewith, this action being against the iniuence of the spring 89 and acting to compress said spring; and when the c am sleeve is rotated in the reverse direction the spring 89 in reacting will push the clutch drum inwardly away from the clutch the clutch drum so that it will be wound thereon in the rotation ofthe drum, and has 1 to the position shown in Fig effected b et its rear end connected with the lower end of the extension 68 ofthe lever 65 before alludedto, the result being that as the clutch drum. is rotated when in driving engagement with the clutch member, the chain will be wound thereon and will pull the lower end of. the lever forwardly and swing its upper end rearwardly, and due to the connection of the said lever with the arched axle through the medium of the bracket arm 69 and' link 73 before described, the arched axle will be swung rearwardly and upwardly from the position shown in Fig.

2 as previously described, by which action beam and connected parts will be out of the ground to an inoperative .position as shown in Fig. 2.

The connection of the clutch drum with the clutch member to bring about the power elevation of the parts as just described, is

elevated aft'eXten ng foot lever 95 pivoted between its ends as at 96 to the segment frame on the axis of the pivotal connection of the hand lever 65 with said frame, and having jointed to its forward end the rear end of a link 97, the forward end of which is jointed to the upper end of the clutch actuating arm 93. The construction and relation of the parts is such that when this foot lever is depressed, the cam sleeve 90 will be turned in a counter-clockwise direction and the clutch drum will be pushed outwardly into driving engagement with the clutch member, whereupon the rotation of the clutch member will be imparted to the clutch the chain will be wound thereon and the plow beam and connected parts elevated. It is necessary before the parts can be thus elel vated, to unlock the hand lever from the segment frame, and this unlocking is effected automatically by the depression 0f the foot lever, through the medium of a vertically movable lever 98 pivoted at its forward end to theysegment frame asfat 99 and extending rearwardly above the foot lever in such position that when the rear end of the plow means ofa horizontal fore and drum,

the foot lever is depressed its forward end will engage the lever 98 and move the same vertically. v To the rear end of the lever 98 is jointed "the lower end of a link 100` which has formed on its upper end a lateral eye 100iL encircling the upper end of the latch between the head 78 on the latch rod and the guiding lug 77b on the hand lever, the result being that when the lever 98 is moved vertically by the depression of the foot lever, the eye 100a on the link 100 will engage the head 78 on the latch rod and will thrust the latch rod outwardly and thereby correspondingly move the latch and disengage the same from the forward notch in the segment frame in which it was for the time being entered. It is seen therefore that the effect of depressing the foot lever 95 is first to unlock the hand lever from the segment frame and thereby release the beam from its locked depressed position, and next to actuate the cam sleeve 90 andconnect the clutch drum in driving engagement with the,

clutch member. Inthe lifting operation described, the latch after it is disengaged from the forward notch will, as the lever 65 swings rearwardly away from lever 98 toward the rear notch 76, ride upon the outer periphery of the segment frame until the notch 76 is reached, whereupon the latch will be projected into said notch by its spring. By this automatic engagement of the latch, the driver is given warning that the plow is fully raised and locked in that position, whereupon he releases the pressure of his foot on the foot lever and the latter will be swung upwardly to itsl former position by means of a spiral spring 101 connected at its rear end to the forward end of the foot lever and connected at its opposite end to a fixed arm 10Ql on the machine frame. upward movement of the foot lever in this manner will thrust link 97 forwardly and slightly by the engagement of the lug 77b on the hand lever with the eye 100"'- on the link 100, which engagement is due to the relation of the pivotal axis of the hand lever to the pivotal axis of lever 98, the result being that when the hand lever reaches its rear position ready for the seating ofthe latch e rear notch, the eye 100il on the link 77b and out of engage- 100 will rest on lu dg78 on the latch rod, and

ment with the hea will not therefore the clutch .member by interfere with the descent The of the latchy rod in the seating of the latch. The parts will thus be locked in their elevated positions and the clutch drum disengaged from the driving clutch member.

`When 4the plow is to be lowered, the hand lever is unlocked from its rear position by the release of the locking latch by operating the handle 79, whereupon the weight of the parts assisted by a spring A will cause them to descend. Y I. deem this capabilit gage automatically the foot lever is still depressed, as of importance and advantage for the reason that the driver will be permitted to give his full "attention to the guiding of the horses in making the turn at the ofthe latch to enout being concerned with the precise mofment of the seating of 20 the latch, as would otherwise be necessary if the seating of the latch were dependent upon the 1release of the foot `lever. The foot lever is operated to effect theelevation ofthe furrow opener yat the moment when the machine reaches the end of the field, and by the use of my improved construction the loperator after having depressed the foot lever to initiate the action of the power elevating means, keeps the lever depressed until by'the automatic seating ofthe latch as described, he is apprised of the fact that the parts are fully raised. In the meantime he is devoting his full attention to guiding the horses to makev a complete and proper turn, and when he hears the click of the latch as it is seated byits spring, he can then release the foot lever so that the clutch members of the power mechanism willi be disengaged.

ln order that the machine frame may be adjusted laterally with reference to the furrow opener or plow, to the endthat the press wheels may be caused to follow accurately in the line of the furrow, the bearing 12 in which the arched axle is mounted at one side is sustained by the machine frame in such manner that it may be adjusted relatively thereto in a fore and aft direction. rIhis adjustment is eected as shown more particularly in Fig. 15, where it will be seen that the bearing is seated ina horizontal opening in the lower part of the depending hanger bracket 12b, Whichopening is of such size that the bearing may be shifted horizontally in a fore and aft direction therein to a limited extent. The bearing at its front end is acted -on by a front adjusting screw 110 screwed in the of the opening with its inner end engaging the forward end of the bearing, and at its rear end the bearing is acted on by a similar adjusting screw 111, threaded in the rear wall of the opening with its inner end engaging the rear end of the bearing. By loosening up the rear screw and tightening up the forward screw, the bearing will be in t e rear notch, while ends of the field, withforward wall i shifted rearwardly with the result that the` j frame will be swung at its rear to the right and will carry the press wheels in corresponding direction; and when theforward screw is Sloosened up and the rear screw tightened up, the bearing will be shifted forwardly in the opposite direction, thereby swinging the rear end of theV frame to the left. By this means the press wheels may be nicely -adjusted and caused' to follow the furrow accurately and thereby press the dirt evenly upon the planted seed.
